America's President-elect signed a public letter in 2009 calling for cuts to America's greenhouse-gas emissions. Three years later, he dismissed climate change as a Chinese hoax. When he needed votes he promised to withdraw from the Paris climate agreement. After he was elected he admitted to "some connectivity" between climate change and human activity. And then there was the wall he wanted to build at his luxury resort in Ireland to protect his property from the impact of climate change. More recently, a Trump transition official said that the new President might try to eliminate NASA's Earth Sciences department. And the President-elect in December said, "Look, I'm somebody that gets it, and nobody really knows. It's not something that's so hard and fast." (More on this insane flip-flopping is here.)
